Response: Cannabis is the third most used drug globally, after alcohol and nicotine. Experimental studies show that THC, the main psychoactive component, causes intoxication, cognitive impairments, as well as symptoms of anxiety and psychosis-like experiences and these effects are dose-dependent, which means that higher potency cannabis products (products with high THC concentrations) could increase the risk of harm to cannabis users. 

Previous studies have shown that concentrations of THC in cannabis have increased over the years. In the US and Europe concentrations of THC in cannabis have more than doubled over the past 10 years. In addition, new legal markets have facilitated the appearance of cannabis products with higher potencies than earlier products, such as cannabis concentrates. We also know from previous studies that cannabis use is associated with mental health disorders and 22% of people who use cannabis are estimated to meet the criteria for cannabis use disorder (CUD) or cannabis addiction. 

International increases in cannabis potency and the availability of higher potency cannabis products makes it especially pressing to understand the association of cannabis potency with mental health outcomes.

Older Adult Black Men at Disproportionate Risk of Fatal Opioid Overdose

PainRelief.com:  What is the background for this study?

Response: This study came about because we were looking at data for Cook County, Illinois and saw an increase in older adult opioid overdose deaths.  That made us wonder if there was a national trend or the observation was limited to our local area.  We undertook the research to determine that and found that it is indeed a national phenomenon.

PainRelief.com:  What is the background for this study?  What are the main findings?

Response: People with chronic pain who use long-term opioids face a number of health risks, and often do not have optimally controlled pain.

Buprenorphine acts on the opioid receptor with a different effect than drugs like morphine or oxycodone, and as a result is less associated with the risks of long-term opioid use, such as accidental overdose. While buprenorphine has been successfully used in patients with opioid use disorder for several years, certain experts have proposed using buprenorphine for pain management in people with chronic pain. We found low quality evidence supporting pain control that may be superior to traditional opioids, but much more research is needed to confirm.
